FIELD OF THE INVENTION

This patent application relates to new antiparasitic compounds, compositions comprising the compounds, and methods of using the compounds to prevent, treat and/or control parasites that harm animals and humans.

BACKGROUND OF THE INVENTION

Animals, such as mammals and birds, are often susceptible to parasite infestations. These parasites may be ectoparasites, such as fleas and ticks. Animals and humans also suffer from endoparasitic infections including, for example, helminthiasis which is most frequently caused by a group of parasitic worms described as nematodes or roundworms. These parasites cause severe economic losses in pigs, sheep, horses, and cattle as well as affecting companion animals (e.g. cats and dogs) and poultry. Endoparasites include those which occur in the gastrointestinal tract of animals and humans such as from the genuses Ancylostoma, Necator, Ascaris, Strongyloides, Trichinella, Capillaria, Toxocara, Toxascaris, Trichuris and Enterobius. Other parasites which are found in the blood or other tissues and organs include filarial worms and the extra intestinal stages of Strongyloides and Trichinella.

One type of endoparasite which seriously harms mammals is Dirofilaria immitis, also known as Heartworm. Other filarial endoparasites include Dirofilaria repens and Dirofilaria honkongensis, which can also infect humans. The most common hosts are dogs and cats but other mammals such as ferrets and raccoons may also be infected. Heartworms go through several life stages before they become adults infecting the pulmonary artery of the host mammal. The worms require the mosquito as an intermediate host to complete their life cycle. The period between the initial infection when the dog is bitten by a mosquito and the maturation of the worms into adults living in the heart and pulmonary arteries is six to seven months in dogs and is known as the “prepatent period.” L3 larvae migrate during blood feeding of the mosquito to the tip of the mosquito's mouth parts (labium), leave the mosquito, and are deposited on the skin of the dog where they then migrate through the bite wound into the host. Most L3 larvae molt to fourth-stage larvae (L4s) in canine subcutaneous tissues within 1-3 days after infection. Then, they migrate to the muscles of the chest and abdomen, and 45 to 60 days after infection, molt to the fifth stage (L5, immature adult). Between 75 and 120 days after infection, these immature heartworms then enter the bloodstream and are carried through the heart to reside in the pulmonary artery. Around seven months after infection, Dirofilaria immitis adults reach maturity and sexually reproduce in the pulmonary arteries and right ventricle. Adult males are around 15 cm in length, and females are around 25 cm in length and their normal life span as adults is calculated to be about 5 years.

Heartworm infection is a severe and life-threatening disease. Canine heartworm infection is preventable and prophylaxis treatment is a priority in heartworm endemic areas. Treatment of mature heartworm infection with an adulticide (e.g. melarsomine dihydrochloride) is costly and can cause serious adverse side effects, thus prevention by monthly administration of drugs that interrupt larvae development is widely used. The goal of marketed heartworm preventive therapies in dogs is to prevent the development of the parasite to adult heartworms by interrupting the Dirofilaria immitis life cycle post-infection.

The macrocyclic lactones (MLs, e.g. ivermectin, eprinomectin, milbemycin oxime, moxidectin, and selamectin) are the most commonly used chemoprophylaxis agents and are administered at monthly or six-month intervals. These drugs have been effective against Dirofilaria immitis infective third-stage larvae (L3) deposited by the mosquito as well as maturing fourth-stage larvae (L4). When administered monthly, MLs kill L3 and L4 larvae acquired within the previous 30 days, and thus prevent disease caused by adult worms. MLs can also be used monthly in infected dogs to suppress reproduction in adult worms and remove microfilariae, thereby reducing transmission and gradually causing the attrition of adult worms (Vet. Parasitol. 2005 Oct. 24 133(2-3) 197-206).

In recent years, an increased number of lack of efficacy (LOE) cases have been reported, in which dogs develop mature heartworm infections despite receiving monthly prophylactic doses of macrocyclic lactones drugs. For example, Atkins et al., (Vet. Parasitol. 206 (2014) 106-113) recently reported that an increasing number of cases of dogs that tested heartworm antigen positive while receiving heartworm preventive medication which suggests that some populations of Dirofilaria immitis have developed selectional resistance to heartworm preventives (see also Blagburn et al., “Evidence of genetic selection following treatment of heartworm-infected, microfilaremic dog with increasing dosages of ivermectin,” 58^(th) annual meeting of American Association of Veterinary Parasitologists, p. 64, 20-23 Jul. 2013 American Heartworm Society, 2010. Heartworm Preventive Resistance. Is it Possible, vol. 37. Bulletin of the American Heartworm Society, pp. 5.). Bowman also reviews various studies in which LOE to macrocyclic lactone treatment have been observed from peer-reviewed journals, reports to the Center for Veterinary Medicine (CVM) of the Food and Drug Administration in the U.S. (Bowman, Parasites & Vectors 2012, 5:138). Pulaski et al. described the establishment of macrocyclic lactone resistant Dirofilaria immitis isolates in experimentally infected dogs (Pulaski et al., Parasites & Vectors 2014, 7:494). Similarly, Snyder et al. report a controlled laboratory study with a recent isolate of Dirofilaria immitis, in which treatment with ivermectin and milbemycin oxime did not prevent maturation of inoculated L3 stage larvae. Blagburn et al. describe the comparison of four commercial heartworm preventative therapies against the MP3 laboratory strain of Dirofilaria immitis in which three of four products failed to prevent infections with adult heartworms (Blagburn et al., Veterinary Parasitology, 2011, 176, 189-194. Further reports of evidence of macrocyclic lactone resistant isolates of Dirofilaria immits are reported in Bourguinat et al., Veterinary Parasitology, 2011, 181, 388-392; Geary et al., Topics in Companion Animal Medicine, 2011, vol. 26, no. 4, p. 187; Trends in Parasitology, October 2004, vol. 20, no. 10, p. 477; Bourguinat et al., Veterinary Parasitology, 2011, 176, p. 374-381. In addition, WO 2016/161369 describes in the examples a study in which treatment of dogs infected with L3 stage Dirofilaria immitis of the JYD-34 isolate were treated with an ivermectin oral solution, Profender® Tablets (emodepside+praziquantel) or a combination of an ivermectin oral solution and Profender® Tablets at two dosages. The ivermectin and Profender® Tablet groups resulted in less than 50% efficacy and the lower dosage of the ivermectin+Profender® Tablet group resulted in only 81% efficacy. Thus, there is an ongoing need to develop new anthelmintic agents with improved activity against Dirofilaria immitis and other endoparasites.

Definitions

It is noted that in this disclosure and particularly in the claims and/or paragraphs, terms such as “comprises”, “comprised”, “comprising” and the like can be interpreted as “includes”, “included”, “including”, and the like; and that terms such as “consisting essentially of” and “consists essentially of” are interpreted as allowing for elements not explicitly recited, but excluding elements that are found in the prior art or that affect a basic or novel characteristic of the invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which this invention belongs at the time of filing. Terms not specifically defined herein should be given the meanings that would be given to them by one of skill in the art in light of the disclosure and the context. The meaning and scope of terms should be clear; however, in the event of any latent ambiguity, definitions provided herein take precedent over any dictionary or extrinsic definition. Further, unless otherwise required by context, singular terms shall include pluralities and plural terms shall include the singular. Herein, the use of “or” means “and/or” unless stated otherwise. Furthermore, the use of the term “including”, as well as other forms such as “includes” and “included” is not limiting. As used in the specification, however, unless specified to the contrary, the following terms have the meaning indicated and the following conventions are adhered to.

In the groups, radicals, or moieties defined herein, the number of carbon atoms is often specified preceding the group, for example, C₁₋₆-alkyl means an alkyl group or radical having 1 to 6 carbon atoms. In general, in groups like HO, H₂N, (O)S, (O)₂S, NC (cyano), HOOC, F₃C or the like, the skilled artisan can see the radical attachment point(s) to the molecule from the free valences of the group itself. For combined groups comprising two or more subgroups, the last-named subgroup is the radical attachment point, for example, the substituent “aryl-C₁₋₃-alkylene” means an aryl group which is bound to a C₁₋₃-alkyl-group, the latter of which is bound to the core or to the group to which the substituent is attached.

In case a compound of the present invention is depicted in the form of a chemical name and as a formula, in case of any discrepancy the formula shall prevail. An asterisk may be used in sub-formulas to indicate the bond which is connected to the core molecule as defined.

The numeration of the atoms of a substituent starts with the atom which is closest to the core or to the group to which the substituent is attached. For example, the term “3-carboxypropyl-group” represents the following substituent:

wherein the carboxy group is attached to the third carbon atom of the propyl group. The terms “1-methylpropyl-”, “2,2-dimethylpropyl-” or “cyclopropylmethyl-” group represent the following groups:

The asterisk or “ ” may be used in sub-formulas to indicate the bond which is connected to the core

molecule as defined.

The term “substituted” as used herein, means that one or more hydrogens on the designated atom are replaced by a group selected from a defined group of substituents, provided that the designated atom's normal valence is not exceeded, and that the substitution results in a stable compound. Likewise, the term “substituted” may be used in connection with a chemical moiety instead of a single atom, e.g. “substituted alkyl”, “substituted aryl” or the like.

Unless specifically indicated, also “pharmaceutically acceptable salts” as defined in more detail below shall encompass solvates thereof such as for instance hydrates.

In general, substantially pure stereoisomers can be obtained according to synthetic principles known to a person skilled in the field, e.g. by separation of corresponding mixtures, by using stereochemically pure starting materials and/or by stereoselective synthesis. It is known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis, e.g. starting from optically active starting materials and/or by using chiral reagents.

Enantiomerically pure compounds of this invention or intermediates may be prepared via asymmetric synthesis, for example by preparation and subsequent separation of appropriate diastereomeric compounds or intermediates which can be separated by known methods (e.g. by chromatographic separation or crystallization) and/or by using chiral reagents, such as chiral starting materials, chiral catalysts or chiral auxiliaries.

Further, it is known to the person skilled in the art how to prepare enantiomerically pure compounds from the corresponding racemic mixtures, such as by chromatographic separation of the corresponding racemic mixtures on chiral stationary phases; or by resolution of a racemic mixture using an appropriate resolving agent, e.g. by means of diastereomeric salt formation of the racemic compound with optically active acids or bases, subsequent resolution of the salts and release of the desired compound from the salt; or by derivatization of the corresponding racemic compounds with optically active chiral auxiliary reagents, subsequent diastereomer separation and removal of the chiral auxiliary group; or by kinetic resolution of a racemate (e.g. by enzymatic resolution); by enantioselective crystallization from a conglomerate of enantiomorphous crystals under suitable conditions; or by (fractional) crystallization from a suitable solvent in the presence of an optically active chiral auxiliary.

The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of animals without excessive toxicity, irritation, allergic response, or other problem or complication, and commensurate with a reasonable benefit/risk ratio.

Biological Example 1: Screening Method to Test Activity of Compounds Against Microfilaria of Dirofilaria immitis

Four hundred to six hundred microfilariae of Dirofilaria immitis were added to wells of a microtiter plate containing RPMI media and the test compound formulated in 100% DMSO. Plates were held for three days at 37° C. and 5% CO₂. The efficacy of a compound was determined based on the motility of the microfilaria as compared to average motility of control wells containing DMSO only. A dose response assay was conducted to determine an EC₅₀ value. Compounds A468, A470, A480, A482, A508, A510, A514, A529, A536b, A538, A543, A547, A548, A552, A556, A561, A562, A563, A564 and A567 exhibited EC₅₀ values between 1000 nM and 10000 nM.

Biological Example 3: Screening Method to Test Activity of Compounds Against L4 Stage Larvae of Dirofilaria immitis

Four to six L4 stage Dirofilaria immitis worms are added to wells of a microtiter plate containing maintenance nutrient media and the test compound formulated in 100% DMSO. Plates are held at 37° C. and 5% CO₂ for three days and then assessed to determine the motility of the larvae. Efficacy of a compound is determined by comparison of the treated L4 motility of the relative to the average motility of worms in control wells containing DMSO only.

Biological Example 4: In Vivo Efficacy Against the Resistant JYD-34 Isolate of Dirofilaria immitis in Immune-Deficient (NOD-scid-gama, NSG) Mice

The efficacy of the compounds of the invention against a resistant isolate of Dirofilaria immitis (JYD-34 isolate) was evaluated in immune-deficient mice (NOD-scid-gama, NSG) as an intermediate host of the parasite (see WO 2018/148392 A1). Mice were infected with approximately 50 third stage Dirofilaria immitis (JYD-34 isolate) by subcutaneous injection on Day 0. Mice were treated orally with the placebo and test articles at a dosage of 25 mg/kg body weight on Day 1, Day 15, and Day 30. The dose of 25 mg/kg in the rodent model is believed to be equivalent to a dose of 5 mg/kg in dogs. Fifteen days after the last dose, at Day 45 after treatment, mice were euthanized, and live Dirofilaria immitis larvae were recovered from tissues and counted.

In this model, compound A491 exhibited efficacy of <50%; compounds A465, A484 and A495 exhibited efficacy between 50% and 70%; compounds A464, A486, A471, A481, A489, A501, A502 and A566 exhibited an efficacy of between 70% and 90%; and compounds A472, A473, A493, A504, A507, A522 and A530 exhibited efficacy of >90%. Mice treated with the macrocyclic lactone ivermectin dosed orally at a dosage of 0.2 mg/kg exhibited efficacy of <50%. For comparison, the recommended minimum dose level of ivermectin for dogs in the commercial product HEARTGARD® Plus (ivermectin/pyrantel) is 6 μg/kg.

Biological Example 5: Comparison of In Vivo Efficacy Against the Resistant JYD-34 Isolate of Dirofilaria immitis in Immune-Deficient (NOD-scid-gama, NSG) Mice with Closest Prior Art Compound

It has been found that the compounds of the invention having the bicyclic pyrrolopyridazine core structure are highly efficacious against immature stages of Dirofilaria immitis such as microfilaria and the L4 stage worm, including Dirofilaria immitis isolates that have been shown to be resistant to macrocyclic lactone treatment. Such resistant isolates of Dirofilaria immitis include the JYD34 isolate and others. Importantly, the compounds of the invention having the 5-6 fused bicyclic pyrrolopyridazine core structure demonstrate surprising and unexpected superior efficacy against immature stages of Dirofilaria immitis compared with compounds having a different 5-6 fused nitrogen-containing bicyclic core but having the same substituents around the bicyclic core.

Using the in vivo protocol described in Biological Example 4 above, the efficacies of Compound A465 of the present invention and prior art compound 156 described in WO 2020/014068 (see page 124) were evaluated. The compounds described in WO 2020/014068 include a different 5-6 fused bicyclic ring core (pyrazolo[1,5-a]pyridine) compared with the pyrrolopyridazine core ring system of the compounds of the invention. With the exception of the different core ring systems, compound A465 and prior art compound 156 contain the same substituents around the bicyclic ring. The structures of compound A465 of the invention and prior art compound 156 are shown below for illustration:

In this in vivo model system, compound A465 exhibited an efficacy of 68% while compound 156 exhibited an efficacy of 29% at a dosage of 25 mg/kg. The difference in efficacy is significant in this model. This example clearly shows the importance of the pyrrolopyridazine bicyclic ring on the in vivo efficacy of the compounds against a resistant isolate of Dirofilaria immitis. As illustrated by the two structures above, with the exception of the bicyclic ring systems, the substitution pattern of the compounds is exactly the same.

Biological Example 6: In Vivo Efficacy Against the Resistant JYD-34 Isolate of Dirofilaria immitis in Dogs

Beagle dogs were tested for microfilaria and heartworm antigen and received a full physical examination prior to inclusion in the study. Each dog was inoculated with 50 infective third-stage D. immitis larvae on Day −30 using the JYD-34 isolate which has been demonstrated to be resistant to macrocyclic lactones. Antigen testing performed on blood collected on Day 90 confirmed that animals had not been exposed to D. immitis prior to the induced infection.

Dogs were ranked by decreasing body weight within sex to form blocks of eight dogs each with approximately equal numbers of each sex and randomly assigned to each treatment group. Each study group contained five dogs. Dogs in the negative control group (Group 1) were untreated. Dogs in Group 2 were treated orally four times at monthly intervals with the commercial product Interceptor™ (milbemycin oxime) according to the product label. Dogs in Groups 3 and 4 were treated orally four times at monthly intervals (Days 0, 27, 55 and 84) with capsules containing an oral solution of Compound A471 and A464, respectively, at a dosage of 5 mg/kg body weight. On study day 120 dogs were euthanized and necropsied for evaluation of the presence adult heartworms. The results of the study are shown in Table 5 below.

TABLE 5 Efficacy against D. immitis in beagles. Geometric Mean Live Trt. Investigational Heartworm % Group Material Dose Count Efficacy 1 (−) control n/a 27.1 n/a 2 Interceptor ™ 0.5 mg/kg 21.2 21.8 (milbemycin oxime) 3 A471   5 mg/kg 16.5 39.0 4 A464   5 mg/kg 16.7 38.2

As shown in Table 5, compounds A471 and A464 of the invention were found to be more effective than the commercial product Interceptor™ administered according to the label dose against the resistant JYD-34 isolate of Dirofilaria immitis.

Biological Example 7: In Vivo Efficacy at Two Dosages Against the Resistant JYD-34 Isolate of Dirofilaria immitis in Dogs

In a further in vivo study conducted according to the procedure described in Biological Example 6 above, the efficacy of compounds A481 and A493 was tested against a resistant heartworm isolate (JYD-34) in beagles at two different dosage rates compared with a negative control group (Group 1) and a positive control group (Group 2) treated with Interceptor™ (milbemycin oxime). The objective of dosing the test compounds, in the higher dosage rate, on consecutive days was to evaluate the impact of increased exposure to the compounds on the efficacy against heartworm. Given the length of the heartworm lifecycle for the target L4 stage worm (see, for example, page 1, line 25 to page 2, line 10) and the study duration, it is considered that splitting the total dose into two administrations on consecutive days would not adversely impact the study outcome. In the study, Group 3 was treated with Compound A481 at a dosage of 5 mg/kg body weight on days 0, 27, 55 and 84. Dogs in Group 4 were treated with Compound A481 at a dosage of 5 mg/kg body weight on days −1, 0, 26, 27, 54, 55, 83 and 84. Similarly, dogs in Group 5 were treated with Compound A493 at a dosage of 5 mg/kg body weight on days 0, 27, 55 and 84, and dogs in Group 6 were treated with Compound A493 at a dosage of 5 mg/kg body weight on days −1, 0, 26, 27, 54, 55, 83 and 84. The results of the study are shown in Table 6 below.

TABLE 6 Efficacy against D. immitis in beagles at two dosages. Geometric Mean Live Trt. Investigational Heartworm % Group Material Dose Count Efficacy 1 (−) control n/a 31.5 n/a 2 Interceptor ™ 0.5 mg/kg 5.6 82.1 (milbemycin oxime) 3 A481 5 mg/kg 11.3 64.2 4 A481 10 mg/kg (over 2 0.6 98.0 consecutive days) 5 A493 5 mg/kg 0.3 99.0 6 A493 10 mg/kg (over 2 0 100.0 consecutive days)

As shown in Table 6, compounds A481 and A493 are highly efficacious against the resistant JD-34 isolate of Dirofilaria immitis compared with the positive control. It is important to note that the Interceptor™ group (Group 2) was dosed monthly according to the product label while the optimum dosage of the test compounds has not yet been determined. It is also noted that the efficacy of the Interceptor™ group (Group 2) in the present study was significantly higher than the efficacy observed in the studies described in Biological Example 6 and Biological Example 9 (below). Compounds A481 and A493 exhibited efficacy of about 98% and 100% against the resistant JYD-34 isolate of Dirofilaria immitis at a dosage of 5 mg/kg administered monthly for four months on two consecutive days, while Compound A493 exhibited efficacy of 99% when one single dosage at 5 mg/kg was administered monthly for four months. These results against a resistant isolate of Dirofilaria immitis are significant and surprising.

Biological Example 8: In Vivo Efficacy Against Resistant JYD-34 Isolate of Dirofilaria immitis in Dogs

In a further in vivo study using the procedure described in Biological Example 6, the efficacy of compound A472 was tested for efficacy against a resistant heartworm isolate (JYD-34) in beagles compared with a negative control group (Group 1) and a positive control group (Group 2) treated with Interceptor™ (milbemycin oxime). In this study, Compound A472 was found to be 100% efficacious at preventing infections with adult heartworm when administered in a dosage of 5 mg/kg body weight monthly for four months. In comparison, the milbemycin oxime control group was only found to be 16.6% efficacious. Table 7 below summarizes the results of the study.

As shown above in comparison with the commercial product Interceptor™ (milbemycin oxime), the excellent in vivo efficacy of the compounds of the invention against a resistant isolate of Dirofilaria immitis is noteworthy and demonstrates the inventiveness of the compounds described herein.
